Electrifying brain circuits could treat neurological and psychiatric symptoms not because it causes neurons to fire but it creates an environment that makes it more or less likely for neurons to fire, researchers, including one of Indian-origin, have found.

Alcohol can reduce firing of neurons or brain circuits, which is why it reduces anxiety and social inhibitions, and those who are less sensitive to motor-impairing effects of alcohol are likely to drink much, the researchers said.

Using stem cells derived from human skin cells, US researchers have revealed that these can be turned into retinal ganglion cells (RGCs) -- the neurons that conduct visual information from the eye to the brain -- to prevent or cure glaucoma.

Just as most of the world's air travel passes through a few major hubs, the majority of information in the brain flows through similarly well-travelled routes, a team led by an Indian-origin researcher from Indiana University has found.

Facebook is releasing for free the designs of a new computer server - twice as fast as those used by Facebook earlier, it designed to put more power behind artificial-intelligence software, MIT Technology review reported.

When the brain forms memories or learns a new task, it encodes the new information by tuning connections between neurons. Now, neuroscientists have discovered a novel mechanism that contributes to the strengthening of these connections, called synapses.
